Texans lost a more sustainable way of traveling the Lone Star State this month.

Megabus, the cheap and efficient bus company that offered rides for as low as $1, has ended service across Texas, including all routes operating between Austin, Dallas, Grand Prairie, Houston, and San Antonio.

According to a notice on the company's website, they shut down the Texas routes on August 16 as part of a set of new nationwide route changes that also included offloading other routes to competing operators.

Known for its eye-catching double-decker royal blue buses, Megabus was first launched in the U.K. in 2003, then came to the U.S. in 2006. It generated considerable excitement when it entered the Texas market in 2012, by offering free Wi-Fi, restrooms, and fares for as low as $1.

The changes come after Coach USA, Megabus' owner, filed for Chapter 11 bankruptcy, winning court approval to sell its Megabus service in July. The company blamed its bankruptcy on a decline in ridership during the pandemic.

Shutdowns:

  • Routes operating between Atlanta, Charlotte, Durham, Richmond, and Washington, D.C. will be discontinued as of August 16th, 2024. Customers with tickets booked on these services have been notified and refunds have been processed.
  • Routes operating between Dallas, Austin, San Antonio, and Houston will be discontinued as of August 16th, 2024. Customers with tickets booked on these services have been notified and refunds have been processed.

New operators:

  • Routes operating between New York, Baltimore, Philadelphia, and Washington, D.C. will be operated by Peter Pan Bus Lines
  • Routes operating between New York, State College, Harrisburg, King of Prussia, and Pittsburgh will be operated by Fullington Trailways

All other routes in the United States and Canada will operate as normal.

Megabus still operates in more than 500 different cities and university campuses across the U.S., including several popular routes between New York, Philadelphia, and Washington, D.C.

Engie signs deal to supply wind power for Texas data center

wind deal

Houston-based Engie North America, which specializes in generating low-carbon power, has sealed a preliminary deal to supply wind power to a Cipher Mining data center in Texas.

Under the tentative agreement, Cipher could buy as much as 300 megawatts of clean energy from one of Engie’s wind projects. The financial terms of the deal weren’t disclosed.

Cipher Mining develops and operates large data centers for cryptocurrency mining and high-performance computing.

In November, New York City-based Cipher said it bought a 250-acre site in West Texas for a data center with up to 100 megawatts of capacity. Cipher paid $4.1 million for the property.

“By pairing the data center with renewable energy, this strategic collaboration supports the use of surplus energy during periods of excess generation, while enhancing grid stability and reliability,” Engie said in a news release about the Cipher agreement.

The Engie-Cipher deal comes amid the need for more power in Texas due to several factors. The U.S. Energy Information Administration reported in October that data centers and cryptocurrency mining are driving up demand for power in the Lone Star State. Population growth is also putting pressure on the state’s energy supply.

Last year, Engie added 4.2 gigawatts of renewable energy capacity worldwide, bringing the total capacity to 46 gigawatts as of December 31. Also last year, Engie signed a new contract with Meta (Facebook's owner) and expanded its partnership with Google in the U.S. and Belgium.

Houston researchers make headway on developing low-cost sodium-ion batteries

energy storage

A new study by researchers from Rice University’s Department of Materials Science and NanoEngineering, Baylor University and the Indian Institute of Science Education and Research Thiruvananthapuram has introduced a solution that could help develop more affordable and sustainable sodium-ion batteries.

The findings were recently published in the journal Advanced Functional Materials.

The team worked with tiny cone- and disc-shaped carbon materials from oil and gas industry byproducts with a pure graphitic structure. The forms allow for more efficient energy storage with larger sodium and potassium ions, which is a challenge for anodes in battery research. Sodium and potassium are more widely available and cheaper than lithium.

“For years, we’ve known that sodium and potassium are attractive alternatives to lithium,” Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor of Engineering at Rice, said in a news release. “But the challenge has always been finding carbon-based anode materials that can store these larger ions efficiently.”

Lithium-ion batteries traditionally rely on graphite as an anode material. However, traditional graphite structures cannot efficiently store sodium or potassium energy, since the atoms are too big and interactions become too complex to slide in and out of graphite’s layers. The cone and disc structures “offer curvature and spacing that welcome sodium and potassium ions without the need for chemical doping (the process of intentionally adding small amounts of specific atoms or molecules to change its properties) or other artificial modifications,” according to the study.

“This is one of the first clear demonstrations of sodium-ion intercalation in pure graphitic materials with such stability,” Atin Pramanik, first author of the study and a postdoctoral associate in Ajayan’s lab, said in the release. “It challenges the belief that pure graphite can’t work with sodium.”

In lab tests, the carbon cones and discs stored about 230 milliamp-hours of charge per gram (mAh/g) by using sodium ions. They still held 151 mAh/g even after 2,000 fast charging cycles. They also worked with potassium-ion batteries.

“We believe this discovery opens up a new design space for battery anodes,” Ajayan added in the release. “Instead of changing the chemistry, we’re changing the shape, and that’s proving to be just as interesting.”
